FASTENER FOR METALLIC BASH-BARB.

Specification of Letters Patent.

' Patented Nov. 19, 1907.

Application filed January 14.1907- Berial No. 852,178.

To allwhom it may concern:

Be it known that I, GUSTAVUS A. BISCHOFF, a citizen of the United States, residing at Chicago, in the county of Cook and tate of Illinois, have invented certain new and use- 7 fulIm rovements inFasteners for Metallic Sashars, of which the following is a specification.

Thisinvention relates to improvements in a fastener or device to be used for securing together, or 1 rather one on the other, the pieces comprising the sash bars of metallic sashes for windows so that the panes of glassmay be held between said pieces, and while it is more especiall intended for use in connection with the sas bars made of gal- -o 'enings in the vanized iron, yet it is applicable for use in other kinds of metallic sas bars; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the parts thereof, as will be hereinafter more fully'set forth and specifically claimed.

As is well known to those s illed in the art to which my invention ertains, the sash bars of galvanized iron sas es, which support the glass between consist of an inner and outer piece, both of rovided on their adjacent surfaces when 1n position for use with longitudinally extending slots. One of these pieces of the bar, usually the outer one,

has secured, at intervals, to its slotted or-- tion a'series of plates, each of Whic 1s formed with a screw-threaded opening to receive screw-bolts extended through suitable other portion of the sash bar. e; aforesaid lates have heretofore been secured to the plece of the bar on which they are located, so as to extend across the slottherein, and by means of solder or rivets,

which "requires much time and labor, and,

besides,a greatdeal of care in order to properly locate. the o enin s in said plates betweerrthe sides of the s ot in the piece of the sash bar to which they are secured. ur-

thermore, these lat es have squared or rectan ar ends w ch, when in position, rest against the side Walls of the piece of the sash bar, on which they are located, and it has been the custom, in fact the necessity, to insert them at one of the ends of the sash bar piece before said bar piece is laced in os1- tion on the sash, for as the en s of said p ates are squared or rectangular, it is obvious that they could not be turned to a transverse osition with respect to the sash bar piece a ter the sides of the sash frame,

being first inserted longitudinally through the slot therein. A still further difficulty in using said plates has been that great accuracy of their adjustment before being secured to the bar piece was required, so that their openings would be located in the proper places to register with the openings in the other sash bar piece through which the screw-bolts. extend.

The main object of my invention is to avoid or overcome the above-named objections in the old style, or way heretofore practiced, by providing a fastener for securing the ieces of the sash bar one. on the other, whic shall be simple and inexpensive in construction, strong, durable and effective in operation, and so made as to be readil located in operative position on one o the 'gpieces of the sash bar after said bar has been iixed in place on the sash, and in such a manher as to obviate the necessity of fixing the plate portion of the fastener to the sash bar piece on which it is located by means of solder, or otherwise.

Another object is to so construct the fastener that the plate portion thereof will be, in a manner,'self-adju'sting in the sash bar piece in which it is located, so that the openmg in said plate for the screw-bolt may be brou ht into register with an o ening in the sash ar iece in which said boi t is located.

A furtiier object is toso construct the Elite portion of the fastener that it will ly engage the sides of the sash bar piece in which 1t 18 located when the screw-bolt is turned in either direction, thus restricting the movement of and preventing the plate turning therewith, and, besides, causing the openin in the plate for said bolt to be automatica ly located e uidistantly between the adjacent edges of t e slot of the sash bar piece.

Other objects and advantages of the in- 7 tion oflthe astener, illustrat' 4 is an end view of the,

suitable size, form and between saidpieces. Fig. 2 is a lan see tional view taken on line'2.-2 o Fig. 1, orm

Fi late portion of the fastener,- showing a modiiication in theconstruction of its supporting means ,2 and Fig. 5 is a similar view, showing another modification in the means for su porting the late.

ike numera s of reference, refer to corresponding parts throughout the different views of the drawing.

The sash bar, Wl'llCh maybe made of any material, but preferably of galvanized iron and of the shape in cross-section shown in Fig. 2 of the drawing, consists of two pieces secured one on the other, as shown in the lower portion of Fig. 1 and in Fig. 2 of the drawing, and for the sake of convenience I will term one of the pieces, which is designated by the reference numeral 10, as the outer piece, and the other, which is designated by the reference numeral 11, as the inner piece, or mucton by which term sa d inner'piece is known in the trade. As shown in Figs. 1 and 2, the outer piece 10 is provided on each of its side walls with inwardly extendin flanges 12, the free edges of which are space apart to produce a slot 13,

, through which the screw-bolts 14 may pass to engage the holding-plates therefor, and

that the side walls of theinucton or inner piece of the sash bar is formed. or provided with inwardly extending flanges 15, each of which has at its free portion'an outturned part or flange 16 to rest against the surface of the flanges 12 on the outer piece of the sash bar adjacent to the inner piece thereof, the parts 16 being bent substantially at right angles to the flan es 15 and serving to hold said flanges in para distance from the flanges 12 to receive the panes of glass 17 and putty used for securin them in place, when desired. It will'be observed by reference to Fig. 2 that the inner portion bf the flanges 15, as'well as the parts 16, are spacedapart, thus forming a lon 'tudinal slot 18 throughoutthe length 0 the mucton 11 or inner piece, through which'the bolts 14 pass, which bolts are extended through suitable apertures provided in the,

therewith having the plate per-.

In some instances, 1 may dispense with lelism with and at a sufiicient,

sash on the "other, and consists of a belt a hold and-after it is. in

engagement with the bolt, the. other part of the fastener. ,The bolt 14, as shown In. Fig. ,2, is preferably form fed -with ing-platejfor engagement 1 [means to sup ort it until a head 19 on one of its ends. andis screwi threaded, as shown, to engage a: screwthreaded opening 20 in the holding-plate 21,

which is preferably made of metal and of substantially the form as shown in Figs. 2 and 3 of the -drawingthat is to say-said plate has each of its ends formedlwith two equilateral sides which sides are opposed diametrically with respect to the opening 20 in the holdingate. grovided at about the middle of each of its sides with a support or leg 24, the free end of each of which is preferably tapered or formed The holding-plate 21 is formed or- 22 of a triangle, the apexes 23 of angular as at 25, so as-to reduce the friction incident to the contact of said legs or supports with the face or wall of the outer sash bar piece 10, against which they will rest when the holding-plate is positioned in said piece. These legs are preferably bent' towards each other from the side edges of the plate 21, and then slightly bowed as at 26, as shown in Fig. 2, so as to afford a slight yielding or spring-like effect, but this formation thereof is not essential, noris thepointing of the ends of Figs. '2 and 3, a material feature thereof, for .they may be made so as to present straight edges at their free ends, as shown at 4 of the drawingone of the legs or supports anduse one leg 24 therefor, as shown in Fig. 5, which maybe located on one of the side edges of the plate,

or otherwise, and bent with respect to the same, so as to hold the plate against the inner surface of the flanges, 12 when the plate is placed in position in the outer piece 10 of the sash bar. The plate 21 may be provided with a thickened portion 28 around theopening 20, in threads may be formed to engage the bolt.

From the foregoing and by reference to the understood that with any of the supporting'means shown in the drawing and a ove described, said supdrawing it will be clearly seen and 'readily by providing the plate 21 the legs as shown at 25 in which thickened portion 'screw- 1 ports being of metal, which is more or less,

flexible, may be bent so as to be interposed between the plate 21 and the face or wa 1 10 of the outer sash bar piece, and that the plate may be inserted in one end of the sash bar piece 10 and slid therein to about the proper position, the angular ends 23 of the plate contacting with the inner surfaces of the walls of the piece 10, as is clearly shown by continuous lines inFig. 1 of the drawing.

When a number of these plates 21 have been disposed in about their proper positions, the

were

. panes of glass 17 may be positioned with their adjacent edges spaced apart, as shown, when the muctonor inner iece 11 of the sash bar may be applied on t e panes .-17,so that the portions 16 of its flanges 15 willrest against the flanges 12 of the outer iece of the sash bar, when by assing the olts 14 through the o enings in the piece 11 therefor, the inner en s of the bolts may be inserted into the openings 20 of the plates 21,

when said plates may be moved to their correct positions and the bolts tightened so as to securelyhold the pieces" 10 and 11 of the sash bar together and in position on the panes of glass. In the operation of screwing up or tightening the bolts, it is apparent that the pointed or angled ends 23 of the plates 21 will strike the side Walls of the piece 10 of the sash bar and revent said lates turning with the 1bolts. on it is esired to remove the boltsand they are turned in the opposite directions, it is apparent that t plates may turn therewith until they assume the positions indicated by dotted lines in Fig.

1, when further movement thereof will be prevented, As the opening 20 in each of the plates islocated midway between the angled ends 23 and on a line therewith, it is apparent that when said ends are in contact with the walls of the piece 10, the opening 20 will occupy a position midway between the. sides of the slot 13 and in alinement with the openings inthe piece 11 for the bolts, thus making it an easy matter to insert the bolts into the openings 30, when the plates may be slightly moved to their-dproper positions.

If it is desire inner surfaces of the in p ace on the sash, this'can be done by bending the supports for the late sufiicientl so that it may be passed longitudinal y through the slot 13 of the bar 10, when the late may be turned to the position shown by continuous lines in Fig. 1, and the supports therefor bent outwardly so as to support the plate against the flanges 12 of said sash bar piece.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters-Patent, is-

sisting of an apertured plate having its ends angled to form apexes on a line with said aperture and rovided with means projected beyond one 0 its surfaces to support it, and a screw-bolt in screw engagement with the aperture of said late.

2. A fastener or metallic sash bars consisting of an apertured plate having yielding means projected beyond one of its surfaces to su port it, and a bolt adapted to engage the p ate in said aperture.

3. sistin of an apertured plate having its ends angle to form apexes on a line wit 7 said aperture and provided with yielding supports projected beyond one of its surfaces. to support it, and a bolt in serew engagement with the aperture of the plate.
